Redis at LINE

This document summarizes how LINE messaging uses Redis. It discusses: - How LINE has scaled Redis from 3 nodes in 2011 to over 14,000 nodes today to support over 25 billion messages per day. - The key ways LINE uses Redis, including for storing sequences, caches, secondary indexes, and local queues. - Challenges LINE faced in scaling their in-house Redis cluster to over 1,000 nodes and workarounds

ワイルドに運用されてるという感想。大きいデータストアになってくるとfull syncの問題も出るし大変

local queue, sequence, caches, storages の構成・CPU の数だけ動かす、ディスクレス、独自クラスタ、面白い
